A nurse receives a phone call from the lab about serum potassium levels for a patient and notes 1.5 mEq/L. What priority nursing action should the nurse take?

Choice A rationale

While many Electronic Health Record (EHR) systems offer patient portals that allow access to medical information, this is not a universal or defining feature of all EHRs. The core benefit is the systematic organization of all health information into a single, unified digital record, which improves data accessibility for authorized healthcare providers, enhancing coordination of care and patient safety.

Choice B rationale

This information is incorrect and violates the Health Insurance Portability and Accountability Act (HIPAA). EHRs, like paper records, require explicit client authorization for sharing protected health information with anyone, including a significant other, safeguarding the client's fundamental right to privacy and control over their medical data.

Choice C rationale

This information is incorrect, as using client data for research typically requires de-identification of data or explicit client authorization (informed consent). EHRs follow strict privacy and ethical guidelines; they facilitate research by organizing data but do not override the necessity for regulatory and ethical compliance, including client approval for data usage.

Choice D rationale

The fundamental design principle of the Electronic Health Record (EHR) is to integrate disparate healthcare data—including medical history, lab results (e.g., normal adult BUN is 7-20 mg/dL), imaging, and treatment plans—into one comprehensive electronic chart. This centralized platform eliminates fragmentation, promoting seamless information exchange and better interdisciplinary care coordination.

Choice A rationale

Checking the patient's identification (ID) band and comparing it against the chart information (often using two patient identifiers, such as name and date of birth) is the most fundamental safety step to ensure the correct patient receives care and documentation is accurate. This process verifies the biological match between the patient and the medical record, preventing errors that could lead to severe harm.

Choice B rationale

Skipping identification is a violation of established safety protocols and a major contributor to medical errors, including wrong-patient procedures or documentation errors. Accurate identification is non-negotiable before performing any clinical action, including documentation, as it mitigates the risk of mixing up patient records, which can severely compromise care quality.

Choice C rationale

While asking the patient's name is a good secondary check, it cannot be used as a sole identifier as patients may be confused, non-verbal, or share a common name. The physical verification against the ID band (Choice A) provides an objective link to the medical record, reducing reliance on potentially unreliable verbal responses or memory.

Choice D rationale

Performing a thorough assessment is a critical nursing step for determining the patient's clinical status and care needs, but it is not the primary safety step for chart-entry accuracy. The priority before any intervention or documentation is positive patient identification, which logically precedes the assessment in the safety hierarchy to ensure all subsequent steps relate to the correct individual.
